What will I save on my energy bills with energy efficient windows?
The first thing to highlight is that you can reduce heat loss by as much as 70% when you replace old single glazed windows or cheap double glazing with intelligent A-rated energy efficient windows.
It is not unknown for annual heating bills to drop by £100-£300 per year for homeowners taking up residence in typical semi-detached properties. Savings can exceed that estimate if you live in a detached or particularly large abode because of their enlarged window areas and higher dependency on energy.
Total savings will be determined by other factors too, such as U-values, airtightness and any existing insulation that’s in situ.
Which is the most efficient out of casements, sash and tilt & turn windows?
Sealing has a big hand in determining the standard of energy efficiency offered by different types of windows. Windows are our specialist subject at Visual, so we can guide you through draught proofing windows and the best energy efficient windows.
Draughts and heat loss will be less prevalent with casement windows and tilt and turn windows due to how tightly they close. Air leaks are the biggest drawback of traditional sash windows.
Cheaper heating bills and raised home comfort will be attained with the installation of expertly sealed, high-performance windows.
A, B and C-rated windows – what’s the difference?
They each deliver varied levels of energy efficiency, rated according to how much of it they provide in the Window Energy Rating (WER) system.
A-rated windows succeed in being the most energy efficient and the best at retaining heat and bringing energy costs down. Building regulations stipulate that replacement windows must be at least C-rated, but they won’t save you as much money as A or B-rated windows, nor harvest similar comfort.
A shift from C to A-rated windows will have a dramatic impact, activating improved warmth thanks to fewer draughts and reducing outlay on energy bills.
U-values – what are they all about?
Window replacements all have a designated U-value and what it represents is the quantity of heat that escapes through a window (a low U-value indicates excellent insulation). Typical ranges are:
- Single glazing: 5.0–6.0 W/m²K
- Old double glazing: 2.8–3.0 W/m²K
- Modern A-rated windows: 1.2–1.6 W/m²K
Every homeowner wishes for warmth in the home and inexpensive energy bills and observance of WER ratings and U-values when browsing window designs is how to accomplish the two aspirations. Come along to James Oliver’s Lincoln showroom to view our window sets.
